Hi,
Do you get sound? If sound is also not there, it is the power supply which needs to be looked into. If sound is there, it is the inverter section which needs to be checked.

Can I use my U.S. 42LG70 in Australia?


Two things to consider which will answer this question.

1. The voltage source must be if set from USA 110-120 volts out of the wall outlet (I think it will be but check) and if not you will need a converter that converts that voltage to the USA voltage.

2. Since the transmission format in USA is NTSC and it is PAL there you will need a set top box that converts PAL to NTSC.
( Google PAL to NTSC converter to see those.)

Thats it.

Connecting any outside devices (Wii, DVD player) to my LG 42LG70 results in black and white (Wii) and/or reddish tinted picture (DVD player). Switching to different inputs into the back doesn't cure...


Have you tried another cable or checked to see if the existing one is pushed fully in? This can sometimes be the cause of what you've described.

Dvd player wont work on LG 42LG70 LCD TV. Talked to guy at best buy, says normal cable should work. he thinks there are bad ports on the tv. Thoughts?


Call LG tech support and describe your problem. You could have a bad connection on your main board for the input. Use a different type of connection, if you have tried hdmi, switch to coaxial cable, or use a RGB or standard AV cable and see if the player works. also try dvd player on another tv to see if it functions. hope this helps.
